I look forward to seeing this kind of data on production PNDs. However surely the the processing power of the PNDs would have to be extremely large to cope with real time display of 3D elevation data to the accuracy of 5 metres.
The chance of driver distraction may also be much greater than the current range of PNDs that don't have 3D elevation data.
Tele Atlas is to be commended on the progress of this type of development. However Tele Atlas must not run before it can walk as it mustn't forget that what its customers and subsequently its end users, the general public, need is not flashy gizmos (those can wait) but accurate navigational data.
